Bud, others.
On Harbinger we have a small opening ( delimitation I think ) into the keel area ( lift up the deck hatch near the center of the boat and youd see a small tear in the glass ) and exposed is concrete, led etc. I've been wanting to reseal it with glass but its got too much moisture, I think. For almost two weeks I've had a blower near this opening and stuffing paper towels into it to wick out the moisture. And as expected its always wet in the hole. The hole by the way is about two fingers in size.
How long do I need to wait? Is this damage a concern? Will the wet exposed concrete expand causing my hull to explode?
